Just saw the NTSB spokesman repeating the same BS. They're giving him a few more days before his interview because he's "traumatized". In my experience when an operator is involved in a screwup or even a close call they don't get the kid glove treatment for sure. He is a weird looking guy, I wonder if his lawyer is threatening and demanding special PC treatment because he's a special...person, being ginger and all.
They already have the download from the event recorder and know every thing he did from the moment he took the controls. He will have to explain why he did not slow for the curve. He can have as much time as he wants, there is no good reason short of a massive heart attack which it doesn't look like he had.
